FIELD: chemistry.
SUBSTANCE: method of making assembled components involves assembly thereof and soldering in a vacuum chamber, as well as applying a coating, for example, through contact silver plating, which is carried out after chemical degreasing, insulation of places which are not to be coated, chemical etching, further etching in a mixture of hydrofluoric acid and sulphuric acid, activation in hydrochloric acid, preliminary and chemical nickel plating, as well as chemical copper plating.
EFFECT: disclosed engineering solution simplifies the technology of making sealed lead-ins, enables to obtain improved electrical characteristics of strongly bonded coating and reduce loss, standing wave ratio.
